Log message:
Stop running iwm(4) devices in "continuous active mode (CAM)".
Instead, enable device-level power saving which apparently allows
Tx/Rx RF circuitry to be switched off while inactive to save some power.
Turns out CAM is meant for debugging purposes, not normal operation.
NB: This has nothing to do with 802.11 power saving.
Tested by myself and phessler. There is no visible behaviour change.
